Question

What are the steps to solve x^2+19x=-90

Answer 1

we have the equation

`x^2+19x=-90`

step 1

Rewrite in standard form

`x^2+19x+90=0`

step 2

we have

a=1

b=19

c=90

substitute in the formula

`x=(-19\pm√(19^2-4(1)(90)))/(2(1))`
`x=(-19\pm1)/(2)`

The values of x are

x=-9 and x=-10
